Delta Faucet R10000-PX Universal MultiChoice Universal Rough-In Valve

I apologize if this isn't appropriate, but I couldn't find an admin area or relevant FAQ. Let me know if I need to delete this.

I have an extra bathshower valve for sale if anyone's looking for one. I got it based on this forum, but it's not made for Wirsbo brand pex as it turns out (pex ID too large). I managed to make one work for my upstairs bath (used silicone and fuel injector clamps) but tried many times with the same components to get this one to work downstairs but I kept getting leaks so I bought a different R10000 with the appropriate fittings for my pex.

If you do contact me via CL, let me know you're from this forum so I know it isn't spam as I normally would only deal locally. Thank you!

This valve required the crimp-style pex, not expand-style as I had. Once I swapped to a fully-threaded valve and the appropriate transition fitting for my pex, all was fine. I SHOULD have returned the first one as well, but it had already held for a year the way I did it with no issues so I figured I was good. That's why I was surprised I could never get the other to work the same way.
